Dissolved Air Flotation Unit

The dissolved air flotation unit is made to allow the process in which microscopic air bubbles become attached to solid particles suspended in liquid, causing the solid particles to float. The DAF separator is best used to dissolve air into liquid due to the pressure used, leaving you with microscopic air bubbles. 

The bubbles are thoroughly mixed with the wastewater, attaching to the solids in the waste stream. This causes the air-solid aggregates to rise to the liquid surface, forming a blanket of solids (float). Surface skimmers then remove this float blanket.

 

Features and Benefits

Dissolved air flotation offers several benefits for industrial water treatment, such as enhanced algae removal efficiency, reduced effluent turbidity, rapid startup, and resistance to extreme temperatures. This wastewater treatment system features an air-dissolving and release system and a mixing chamber.

Air Dissolving System 

The DAF treatment process achieves around 90% air dissolving efficiency due to excellent air-to-liquid contact and high mass transfer. This efficiency allows for lower recycling rates and higher wastewater feed rates.

Air Release System 

The Air Release System is engineered to optimise the conversion of air into micro bubbles, achieving over 90% efficiency, with bubble sizes ideally suited for flotation (10 – 100 microns).

Air/Solids/Polymer Mixing Chamber 

The swirl-inducing mixing chamber ensures a thorough mixing of air bubbles, solids and polymer, enabling optimal air/solids bond formation.

 

Applications

The dissolved air flotation system for wastewater treatment has been effectively utilised across a wide range of industries, including food processing, recycling, manufacturing, and mining. It has proven its versatility at various sites, such as food processing plants, mine site wash bays, oily water treatment facilities, garment manufacturing factories, and municipal recycling plants. 

Many industries rely on our DAF systems, backed by decades of experience and a track record of proven results. If you’re seeking a versatile wastewater treatment solution that is clean, efficient, and sustainable, contact our expert team at 02 4954 0440
